2 Sheets-Sheet 2 FIG a I M/VE/Vfol? 76 76 [first SCHRA MA YR HOLDER FOR COLLARS AND THE LIKE GARMENT PARTS This invention relates to an improvement in industrial shirt making machinery and particularly to a holder for collars and the like garments for holding the collars during the manufacture thereof.

Shirt collars are normally made from at least two layers of fabric which are initially stitched together so that the outside surfaces of the finished collars face each other. Prior to turning the thus stitched layers inside out, the excess material outside the stitched line in the area of the collar points must be trimmed to avoid the unsightly bundling of such excess material that would otherwise occur in the vicinity of the collar points.

A machine for trimming the points of collars and other garments has been disclosed in a copending application entitled Automatic Point Trimming Machine for Use in Shirt Making Apparatus and the Like. In such machine, a holder is required for holding the collar while the points are trimmed. On the other hand, a holder is also required for holding the collar while it is stitched on the sewing machine prior to trimming the points.

It is the object of the present invention to provide a holder which may be used with the above-mentioned point trimming machine and also with the sewing machine, that is a holder which may be moved from one machine to the other without removing the collar and the like garment placed therein.

The holder, in accordance with the invention, comprises a base support, a pair of fixed platens secured to the base support, a movable platen hinged upon each of the fixed platens, and means for operating the movable platens so as to permit holding of a collar between the fixed and movable platens.

The above-mentioned operating means includes two members pivotally attached to each other at one end, the first member being pivotally attached at its other end to the fixed platen and the second member being pivotally attached at its other end to the movable platen, and means for locking said two members in substantially aligned relationship for closing the movable platen 'upon the fixed platen.

One of the above members may have a tubular portion into which protrudes a piston against the action of a spring inserted inside such tubular portion. The

above-mentioned locking means may comprise an abutment positioned in such a way that the two members are stopped slightly past the point where their longitudinal axis coincide so that the two platens are locked in contact with each other under the biasing action of the spring in such one member.

In order to unlock the platens, there may be provided apin slidably mounted through the holder and adapted to contact the above-mentioned abutment for moving the two members in the opposite direction, thereby unlocking the platens. A system of levers is mounted on the collar trimming machine for operating the pin to unlock the platens.

The invention will now be disclosed with reference to a preferred embodiment thereof and to the accompanying drawings in which:

FIG. I illustrates a perspective top view of the holder in accordance with the invention;

FIG. 2 illustrates a top view of the holder; and

FIG. 3 illustrates a side view of the holder showing the operation thereof.

Referring to FIGS. 1 and 2, there is shown a holder 10 for a shirt collar including a support 12 upon which are secured two fixed platens 14 and 16. Platen 14 is permanently fixed to support 12 while platen 16 is fixed to support 12 by means of wing nuts 18, the bolts of which are arranged to slide in slots 20 permitting longitudinal sliding of platen 16 with respect to platen 14 for accommodating various sizes of collars.

Upon each one of platens 14 and 16 is hinged a movable platen 22 which is operated by a mechanism 24 to be disclosed later on. A handle 26 is also provided for carrying the holder.

FIG. 1 illustrates an arrangement for positioning the holder 10 with respect to the point trimming machine disclosed in the above-mentioned copending application entitled Automatic Point Trimming Machine for Use in Shirt Making Apparatus and the Like. The arrangement includes generally guide means 28 for positioning a collar on the machine and trimming means 30 for trimming the points. Since the point trimming machine does not form part of the present invention, it has been disclosed in dash lines only and reference to the above-identified application is made for a more detailed description of the machine.

Referring to FIGS. 1 and 3, the means for positioning the holder 10 with respect to the trimming machine comprises a base member 32 secured to the structure of the collar point trimming machine and including two bars 34 and 36 in between which is inserted angle member 38 secured to support 12 by means of bolts 40. The holder is held in position on the machine by its own weight.

It will be easily understood that the holder may thus be easily installed on the point trimming machine with the help of handle 26. In normal operation, the holder is first positioned on the point trimming machine, and a collar is placed on the fixed platens l4 and 16 between the guide means 28 for the trimming means 30. The movable platens are then locked in position over the fixed platens by operating mechanism 24 which will be disclosed more fully in a later part of the application. The holder may then be removed from the point trimming machine for transferring it to the sewing machine for stitching the collar. It is to be understood that a positioning arrangement similar to the one disclosed above will be used for positioning the holder 10 on the sewing machine.

Referring now to FIG. 3, there is shown an enlarged view of the operating mechanism 24. The mechanism includes two members 50 and 52 which are pivotally connected together at one end. The other end of member 50 is pivotally connected to a bracket 54 which is secured to movable platen 22. The other end of member 52 is pivotally connected to a bracket 56 which is secured to fixed platens 14 ot 16. Member 50 includes a tubular portion 58 and a piston 60 arranged to slide therein. Tubular portion 58 also includes a spring 62 which is biased against the end of piston 60 by means of adjustable screw 64 threaded through the base of tubular portion 58. It will be easily seen that each movable platen 22 may be opened and closed by moving handle 66 positioned at the pivotal point of members 50 and 52.

The platens are locked in closed position by lowering handle 66 until abutment 68 of member 52 contacts pin 70 which protrudes through bracket 56. Pin 70 has two collars 72 and 74 which determine the longitudinal movement thereof in bracket 56. Collar 72 of pin 70 is positioned in such a way as to stop member 52 when the two members 50 and 52 have moved slightly past of alignment of their longitudinal axes. In such a position, spring 62 acting on piston 60 holds the two members 50 and S2 and the two platens in a locked position as it will be easily understood.

To release operating mechanism 24, there is provided an arrangement of levers operated by a piston 76, the operation of which may be synchronized with that of the trimming means by any known hydraulic or air circuit. The arrangement of levers comprises a first lever 78 secured to a rod 80 as illustrated in FIGS. 1 and 3. To rod 80 are secured other levers 82 and 84 upon which are welded bars 86 and 88 respectively. When piston 76 is operated, lever 78 rotates bar 80 which in turn rotates levers 82 and 84. The rotation of levers 82 and 84 causes bars 86 and 88 to hit pin 70 associated with each of the movable platens 22. Pin 70 pushes the abutment 68 a distance such as to cause the members 50 and 52 to move past their stable position. A pair of torsional springs 90, as illustrated in FIG. 2, causes the movable platen 22 to continue its upward movement as illustrated by the arrows of FIG. 3 of the drawings.

Although the invention has been disclosed with reference to a preferred embodiment thereof, it is to be understood that various modifications may be made thereto within the scope of the present invention.
